DEVICE OPERATION
PAGE READ
Upon initial device power up, the device defaults to Read1 mode. This operation is also initiated by writing 00h to the command reg-
ister along with three address cycles. Once the command is latched, it does not need to be written for the following page read opera-
tion. Two types of operations are available : random read, serial page read.
The random read mode is enabled when the page address is changed. The 528 bytes(X8 device) or 264 words(X16 device) of data
within the selected page are transferred to the data registers in less than 10
μ
s(t
R
). The system controller can detect the completion
of this data transfer(tR) by analyzing the output of R/B pin. Once the data in a page is loaded into the registers, they may be read out
in 50ns cycle time by sequentially pulsing RE. High to low transitions of the RE clock output the data starting from the selected col-
umn address up to the last column address[column 511/ 527(X8 device) 255 /263(X16 device) depending on the state of GND input
pin].
The way the Read1 and Read2 commands work is like a pointer set to either the main area or the spare area. The spare area of 512
~527 bytes(X8 device) or 256~263 words(X16 device) may be selectively accessed by writing the Read2 command with GND input
pin low. Addresses A

must be "L" in X16 device case. The Read1 command is needed to move the pointer back to the
main area. Figures 8,9 show typical sequence and timings for each read operation.
Sequential Row Read is available only on K9F5608U0C_Y,P or K9F5608U0C_V,F :
After the data of last column address is clocked out, the next page is automatically selected for sequential row read. Waiting 10
μ
s
again allows reading the selected page. The sequential row read operation is terminated by bringing CE high. Unless the operation
is aborted, the page address is automatically incremented for sequential row read as in Read1 operation and spare sixteen bytes of
each page may be sequentially read. The Sequential Read 1 and 2 operation is allowed only within a block and after the last page
of a block is readout, the sequential read operation must be terminated by bringing CE high. When the page address moves onto the
next block, read command and address must be given. Figures 8-1, 9-1 show typical sequence and timings for sequential row read
operation.
